Question

我在主视图控制器中创建了一个简单的按钮。在调用imagePickerController并拍照后，我想将用户重定向到下一个视图控制器以继续处理图像。不知怎的，它总是返回我的主窗口。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString *mediaType = info[UIImagePickerControllerMediaType];

    [self dismissViewControllerAnimated:YES completion:nil];

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        UIImage *image = info[UIImagePickerControllerOriginalImage];

        _imageView.image = image;
        if (_newMedia)
            UIImageWriteToSavedPhotosAlbum(image,
                                           self,
                                           @selector(image:finishedSavingWithError:contextInfo:),
                                           nil);
    }
    else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
        // Code here to support video if enabled
    }
}

为此你必须推动你的观点，如

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    ...

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        ...
        YourImgViewController *imgProcessing = [[YourImgViewController alloc] initWithNibName:@"YourImgViewController" bundle:nil];
        imgProcessing.selectedImageView.image = image;
        [self.navigationController pushViewController:imgProcessing animated:YES];
    }
    else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
        // Code here to support video if enabled
    }
}

非常简单！
